![]() ![]() Through this approach, very large scenes are easier to manage, and the resources needed to deal with them are reduced. At render time, they are passed scene descriptions in the form of a procedural recipe to be run inside the renderer. These are often called deferred evaluation and are able to recursively call other procedurals. Many renderers support procedurals that can be evaluated on demand. ![]() Scalability is also at the heart of rendering in Katana. Currently, Katana ships with the 3Delight renderer and accompanying renderer plugin, and an API that allows developers to support other renderers. The renderer connects to Katana through a renderer-specific plug-in. When it comes to rendering, Katana’s renderer-agnostic nature provides the flexibility to allow CG supervisors and pipeline engineers to select the appropriate renderer for the show or shot. ![]() Solving both problems was essential for dealing with the demands of highly complicated modern productions. Note:To force a reload for a look file that is being resolved, click Flush Look File Cache in the LookFileResolve’s parameters.Katana was developed from the ground up to address the problems of scalability and flexibility. Note:The lookfile.resolvedPass attribute always reports the requested pass and is, therefore, not affected by this fall-back. In this case, no error is generated and the default pass is used, otherwise Katana produces an error location. If no look file pass is specified when attempting to resolve, the pass falls back to the default pass when KATANA_LOOKFILE_DEFAULT_PASS_FALLBACK is set to 1. In the passName parameter, enter the look file pass to use. The LookFileResolve node becomes editable within the Parameters tab. Select the LookFileResolve node and press Alt+ E. To resolve the look file for a particular pass: 1.Ĭreate a LookFileResolve node and connect it to the recipe at the point you want to resolve for a specific pass. The alternate, and preferred method, is to use the LookFileManager node, see Making Look Files Easier with the LookFileManager. In order to apply the changes specified in the look file for a particular pass, use a LookFileResolve node. An attribute on the location, lookfile.asset in this case, stores where to retrieve the look file without actually copying the details to that location. A look file is assigned to a location in much the same way a material is assigned. ![]()
